Bronze Solenoid Valve

Gritty Coolant Valves Full Port

Full Port - Normally Closed - 1/2" to 1" Pipe Size

Max. Fluid Temp. - 212°F | Max. Static Pressure - 300 PSI

No Differential Pressure Required to Open

Operation

Valve opens when energized and closes when de-energized. When the coil is energized the pilot valve opens, relieving the pressure above the piston, which is then lifted from its seat by the plunger. Upon de-energizing the coil, a spring closes the pilot valve and opens a bleed passageway to permit pressure to build above the piston and seat it.

Application

To control the flow of "Coolant", the valve is designed with the piston "turned down" and a larger pilot port, offering additional clearance, allowing the valve to operate with fluids containing some grit/sediment typically found in coolant. Valve operates from zero to maximum differential pressure indicated in table. Valve must be mounted in horizontal pipe with solenoid enclosure vertical and on top.
